Application filed January 4, 1912. Serial No. 669,356.

To all fio/rom 'it may concern Be it known that we, Noni. PARKER Voon wenn and Louis BURN, subjects of the King of Great Britain, residing in London, England, have invented certain new and useful Improvements in Fountains for Decorative Purposes, of which the following is a specification.

This invention relates to fountains for decorative purposes, such as table fountains.

According to the invention, steam is employed to urge the water to issue as a jet from the nozzle of the fountain, by the steam acting directly upon the water in an ejector contrivance.

In order to condense wholly the steam and to cool the water which will have absorbed heat owing to its contact with the steam, preferably, the water traverses a cooling coil of tubing, which may be located in a fountain basin arranged beneath the nozzle, before issuing as a jet or jets. Such a coil will also have a regulating effect upon the jet, preventing the jet issuing in irregular spurts. Instead of a coil, a pressure tank with an air space or cushion may be employed. Conveniently, the water which is caught from the jet in the fountain basin is re-utilized, by the basin serving as the reservoir from which the ejector draws the water, in which case any water which may be lost by evaporation is more or less replaced by the steam which becomes condensed.

Examples of fountains constructed according to the present invention areillustrated on the accompanying drawings, in which z- Figure 1 is a vertical section of a fountain provided with a cooling coil, and Fig. 2 is a vertical section to a larger scale of certain details of construction.

In these views owing to limitation of space the basin of the fountain is shown considerably smaller relatively to the other parts than it is in actual practice.

Referring more particularly to Fig. l, a is a boiler in which steam is generated by any convenient source of heat, indicated by a spirit lamp b. On the top of the boiler a, is fitted a hollow, upright cylinder c, provided at its lower end with a conical valve seat c1. (l is the fountain basin, which is mounted on the hollow cylinder c, which latter protrudes within the basin and is there closed by a perforated cap c2. c is a centrally bored cap screwed over the lower end of the cylinder c, to retain a gauze filter inplace across the bore of the latter. Fitting the valve seat 01, is a spring-pressed valve e. The stem e1 of this valve is bored longitudinally, a conical enlargement f of the bore being formed at the lower end, in which enlargement f is secured an ejector steam nozzle g, which communicates with the interior of the boiler, by means of the gauze-covered lower portion of the bore of the cylinder c. Laterally upwardly inclined passages c2, formed in the valve c, connect the enlarged bore j of the latter with the interior of the cylinder c, and which latter being in communication with the fountain basin CZ, water from the basin has access to the conical enlargement f around the steam nozzle g. The hollow valve stem c1 extends through the perforated cap C2 of the cylinder and is secured to a coupling-piece 7L, between two branches al and 7b2 of which a cooling coil z' is mounted. A pipe y' terminating in a nozzle c is mounted at the upper end of the coupling-piece 7L. The lower portion of the bore of the coupling-piece z, extends at L above its lower branch h1, and such extension by trapping air or steam acts to some extent as a cushion for rendering the jet uniform. The exterior of the upper end of the coupling-piece L is conical and forms a support for a more or less ornamental casng m covering the cooling coil i', which is submerged in the water contained in the basin cl. Should more steam be generated than can pass through the ejector nozzle g, on the pressure becoming sullcient to overcome its spring, the valve c will lift and relieve the excessive steam pressure. Should in such case the escaping steam not become wholly condensed in bubbling through the water contained in the basin, it can readily escape from beneath the casing m, as this latter will be lifted upon its conical support by an accumulation of steam beneath it.

In the construction shown in Fig. 1, the boiler having been initially filled, the fountain will, on the lamp being alight, continue to play until all the water in the boiler has become evaporated, `which will be indicated by cessation 1of the jet. The lamp being then extinguished the boiler will cool down, whereupon the reduction of pressure therein, due to condensation of the remaining steam, will cause water ,from .the basin to be drawn into the boiler from the fountain basin andvthus the boiler willrefill itself.

The water from the fountain device alternatively to issuingias a jet, may be enrv ployed to drive a water ywheel,-.may cascade down a vminiature waterfall or the like, `in Sylvan scenes in shop windows, A@Onservatories, etc.
